    Abstract: An expandable stent for implantation in a body lumen, such as an artery, is disclosed. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so that the stent is flexible in the longitudinal direction. The strength of the stent at a center section or at either end can be varied by increasing the mass of the struts forming each cylindrical element in that center section or end section relative to the lower mass struts in the remaining sections of the stent. Increasing the mass of the struts can be accomplished by, for a given strut thickness, increasing the width of the strut, or increasing the length of a cylindrical element.

    Abstract: The invention is directed to an expandable stent for implantation in a body lumen, such as a coronary artery. The stent consists of radially expandable cylindrical rings generally aligned on a common axis and interconnected by one or more links. At least some of the links are formed of a polymer material providing longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the rings along the longitudinal axis.

    Abstract: An expandable stent design for use in small vessels, such as the distal regions of the coronary arteries, is disclosed. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so that the stent is flexible in a longitudinal direction. The strut width of the interconnecting members is narrower than the strut width of each cylindrical element thereby increasing the flexibility of the interconnecting members relative to the struts of the cylindrical elements. In one particular embodiment of the present invention, the strut width of the connecting segment between alternating peaks and valleys of the cylindrical element is designed to be wider than the width of the strut in the peak and valley portions of the cylindrical element to enhance the radiopacity of the stent. The stent pattern of the present invention is particularly well suited for use in small vessels having diameters of less than three millimeters, such as the distal vessels of the coronary arteries.

    Abstract: An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen for treating an area of vulnerable plaque. The invention provides for a an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. A central section is positioned between distal and proximal sections and is aligned with the area of vulnerable plaque to enhance growth of endothelial cells over the fibrous cap of the vulnerable plaque to reinforce the area and reduce the likelihood of rupture.

    Abstract: Polymeric stents having fracture toughness and resistance to recoil after deployment are disclosed along with methods of manufacturing such stents. Improvements to mechanical characteristics and other improvements may be achieved by having polymer chains within individual stent struts oriented in a direction that is closer to or in line with the axis of the individual stent struts. The desired orientation of polymer molecules may be achieved by one or any combination of extruding polymers into hollow tubes to induce axially oriented polymer chains, applying a tensile load to polymer tubes to induce axially oriented polymer chains, and radially expanding polymer tubes to induce circumferentially oriented polymer chains. Stent patterns include struts defining diamond shaped cells and/or W-shaped cells.
